Parasound A23+ vs. Emotiva XPA-DR2

Choice amplifier for a modest two channel setup.
Do you go for 160w/ch A23+ with better soundstage, greater detail, clarity?
Do you go for 550w/ch DR2 for the punch and impactful sound?
Speakers in play are Paradigm Tributes. Speakers and room work either way.
Which way would you go and why?

(I've looked long and hard and can't find a hint of an actual review on the Emotiva DRs at all. They've been out for a while now.)

Thanks for helping out!
